Japanese Patent JP6837641

B2

PROBLEM TO BE SOLVED: To provide a mounting inspection device of a rail mounting article for determining a mounting status of a rail bond and the like welded (adhered) to a rail by a solder, a brazing metal, and the like.SOLUTION: A mounting inspection device of a rail mounting article includes: a memory part 2 for storing a waveform obtained after a time frequency conversion of a rattling sound obtained by hitting a rail mounting article mounted on a rail; an amplitude determination part 3 for determining a mounting status of the rail mounting article by an amplitude algorithm based on an amplitude ratio of the waveform at a predetermined range; an area determination part 4 for determining the mounting status of the rail mounting article by an area algorism based on an area ratio of the waveform at a predetermined range; and a final determination part 6 for determining a final mounting status of the rail mounting article based on respective determination results of the amplitude determination part and the area determination part. The final determination part 6 determines the mounting status as a "good status" or a "non-good status" based on respective determination results of the amplitude algorism determination part and the area algorism determination part.SELECTED DRAWING: Figure 8
